## Detailed info

## What is Ptero?

Ptero is a free, open-source AI chat platform that routes messages to selected third-party model providers.

## What Ptero does

It supports guest conversations stored in the browser and signed-in Projects stored on its servers. Users select a model, send messages, and manage local conversation backups, while Projects sync chats and custom files across signed-in devices.

## Who Ptero is for

It is for people using AI for informational and conversational purposes who want guest access or synchronized project conversations.

## How Ptero works

Visitors accept the policies, choose a display name, and select a model to start chatting. Regular chats stay in the browser, while GitHub sign-in is required to create and sync Projects; messages are sent to the chosen provider to generate a reply.

## Key features

- Guest access uses a token and display name stored locally.
- Chats outside Projects are kept in the browser.
- Projects store chats and custom files on the server.
- Conversation backups can be exported and imported.
- The site provides access to its source code.

## Facts from ptero.pro, checked 13 October 2026

- Project files are deleted after 90 days without opening Projects.
- The privacy policy says chat content is not used for advertising.

## FAQ

### Are there paid plans?
The terms say the platform is free, with no premium plans, subscriptions, paywalls, or paid tiers.

### Are all conversations stored only locally?
No. Chats outside Projects are local, while Project chats and files are stored on the server and linked to the signed-in account.

### What happens when browser data is cleared?
Local chats and guest identity can be removed, but clearing browser data does not delete server-stored Project data.

### Who processes messages?
Messages pass through the service to the selected third-party AI provider, which applies its own privacy practices.

### How should generated answers be used?
The terms say responses may be inaccurate or incomplete and users are responsible for evaluating their suitability before relying on them.
